2.The Internal Register base address is relocated from $000 to $800 on startup by the

debug utilities (Mon12 and NoICE). To preserve this memory map, you must also do this in your software when booting from flash. To do this, load register $11 with $08 for

example: MOVB #08,$11 ; post-reset location of INITRG

3.The Peripheral Area (A00-BFF) is set to Narrow (8-bit) data width by the debug utilities. If using this memory, you must also do this in your software when booting from flash as

follows:

MOVW #$0CF0,PEAR

MOVB #$73,MISC ; Flash on, p-sel stretch = 3
